oh the joy of getting a quarter from mom or dad, just to get rid of me and enjoy their pizza in peace. Then put the quarter in the cabinet and the little square would bonce off the walls and I move the paddle from top to bottom by turning the knob clock-wise, or counter clock-wise. if timed just right, the paddle would intersect the moving square, and bounce it towards the other side of the screen. This, my friends, was known as PONG!
Don't be jealous.
